Quit my Job

So today I quit my job because my school grades are low and my boss was pissed and just said it was bullshit. Then apparently started celebrating and told my boyfriend's ex😡😡 "well looks like you will be getting a lot of hours." Pissed me off i worked pretty hard and to be treated like that especially by the person who didn't even hire me. Oh well looks like I will just have to look for another job after schools over. Hopefully never fast food again 🙄.
